i got this from some other indian website. i think u can use lemon jiuce, cucumber juice, yogurt, milk, and other things i can't quite remember. but they do seem to work its just the smell. personally i hate milk. eww! the lemon juice worked for me but if u have cuts it stings and soemtimes itches. cucumber juice worked for me too. but if u have a scratch or anything that u dont want to heal into a dark spot u can use lemon juice mixed w/ some of whatever bleaching cream u have that way it wont heal dark. it worked for me. but hey i'm not everybody so....
